Abstract

Summary: Recently, there is a significant rise in the numbers of devices and systems that use industrial, scientific, and medical (ISM) frequency bands. The ISM band is not only used in ISM applications but also in telecommunication services including IMT, Zigbee, Bluetooth, WiFi, WiMAX, WLAN, RFID, military radars, and wireless sensor networks. To cover all these applications, in this paper, a low‐profile planar monopole antenna is suggested for 2.45‐GHz band communication applications. The anticipated antenna is composed of a vertical bar‐shaped radiator and a partial ground plane with two vertical slits. The inclusion of vertical slits in the ground plane forms a matching circuit by enlarging the current path, and hence, the studied design can achieve a measured operating band of 2.2 to 2.95 GHz. Moreover, the studied antenna achieved a maximum peak gain of 2.77 dBi and a maximum radiation efficiency of 82.45% and exhibited an omnidirectional radiation pattern that makes it appropriate for ISM and different narrowband wireless applications. Abstract : A low‐profile planar monopole antenna is presented for 2.45‐GHz band communication applications. The antenna is consisting of a vertical bar‐shaped patch and a partial ground plane with two vertical slits. The slits in the ground plane form a matching circuit by enlarging the current path, and the designed antenna achieved an operating band of 2.2 to 2.95 GHz. The antenna achieved good gain and efficiency and demonstrated an omnidirectional radiation pattern that makes it appropriate for ISM, IMT, Zigbee, Bluetooth, WiFi, WiMAX, WLAN, and RFID wireless communication applications.
